Abstract: 365,350. Fabric for gas cells of aircraft. GOODYEAR TIRE & RUBBER CO., 1144, East Market Street, Akron, Ohio, U.S.A.-(Assignees of Calvert, W. C. ; 2150, 4th Street, Cuyahoga Falls, Akron, Ohio, U.S.A.) Feb. 6, 1931, No. 3834. Convention date, Aug. 8, 1930. [Class 140.] Fabric for gas-cells of balloons and airships is prepared by applying to a base of light fabric inner and outer coatings consisting essentially of rubber, and an intermediate coating comprising polyglycerol and a medium highly resistant to permeation by hydrogen and helium, such as gelatine, casein, agar agar or hµmoglobin. Preferably the inner and outer coatings are blended in progressively decreasing proportions into the intermediate coatings by applying a number of layers of differing composition. In practice, a suitable fabric is spread with a light coating of rubber, preferably on both sides. This is followed by a coat of self-curing rubber cement containing zinc oxide, sulphur, mercaptobenzothiazole, and diethylamine. The third coating consists of rubber latex, and the following coatings consist of mixtures of latex with the medium resistant to permeation by gas, for instance gelatine and polyglycerol. The proportion of gelatine and polyglycerol is increased and the proportion of latex decreased in each succeeding coat until a. number of coats of gelatine and polyglycerol only are applied. Successive coats containing increasing proportions of latex and decreasing proportions of gelatine and polyglycerol are then applied, finishing with a number of coats of latex only. An outer dressing of varnish, lacquer, or rubber may be given, to which paraffin may be applied. Each coat is allowed to dry before applying the next, and the fabric is kept under tension during the coating operation.

Abstract: Chlorinated quinones are obtained from phenolic derivatives of benzene and a -hydroxynaphthalene compounds having the respective general formul  <FORM:0589501/IV/1> and <FORM:0589501/IV/2> wherein X represents H, -OH, -SO3H or -Cl, and wherein the 2, 3, 5, 6, 7 and 8 positions are occupied by hydrogen, chlorine or alkyl (provided at least one such position remains unsubstituted), by halogenation with elemental chlorine in a liquid medium comprising sulphuric acid and a saturated fatty acid containing from one to four carbon atoms.  As starting materials (which must carry no amino substituents) are specified: phenol, p-phenol sulphonic acid, hydroquinone, the chlorophenols, dichlorophenols and sym.-trichlorophenol (which yield chloranil), o- or m-cresol (which yield 3 : 5 : 6-trichloro - 2 - methyl - 1 : 4 - benzoquinone) and 1 - naphthol, 4 - hydroxynaphthalene- 1 -sulphonic acid and 2 : 4-dichloro- 1 -naphthol (which yield 2 : 3 - dichloro - 1 : 4 - naphthoquinone).  Acetic acid is the preferred fatty acid, but formic, propionic or butyric acid may be used.  Benzene derivatives are chlorinated in a medium wherein the concentration of sulphuric acid may reach 75 per cent by weight, but lies preferably between 25 and 55 per cent, the remainder being the fatty acid.  Naphthalene derivatives are chlorinated in a solvent mixture which may contain from 5 to 50 parts of sulphuric acid (96 per cent), from 50 to 95 parts of glacial acetic acid and from 0 to 45 parts of water.  The filtrate remaining after removing the product may be utilized instead of the acid mixtures specified.  Chlorinating catalysts, e.g. iron, antimony, manganese, chromium or their compounds, may optionally be present.  The temperature of the reaction-mixture, after the exothermic reaction has subsided, is preferably kept between 80 DEG  and 120 DEG  C.  In examples: (1) phenol, acetic acid and sulphuric acid are treated in admixture with chlorine substantially at atmospheric pressure, being heated under reflux to 105-115 DEG  C. to obtain chloranil; (2) a -naphthol, acetic acid, sulphuric acid, water and crystalline ferrous sulphate are treated with chlorine at 10-20 DEG  C., raising the temperature gradually to 100 DEG  C. and finally to 120 DEG  C., whilst introducing excess chlorine, to obtain 2 : 3 - dichloro - 1 : 4 - naphthoquinone.

Abstract: 607,840. Automatic firearms. BRISTOL AEROPLANE CO., Ltd., and FONSECA, E. C. M. D'ASSIS-. Feb. 12, 1946, No. 4418. [Class 92 (ii)] Belted ammunition 6 is fed to an automatic firearm 7 by mechanism having control means such as a plate 15, means being provided to receive a loop of the ammunition the arms of which loop are sufficiently close together that the loop is rigid in a lengthwise direction, and the arrangement being such that loads imposed on the plate tending to bring the mechanism into operation are applied to and resisted by the rigid loop. In the construction shown, the belt is assisted towards the gun by spaced sprockets 5 on a shaft driven by a motor which is in circuit with a switch 12. If the gun is fired when the. loop is depressing a spring- pressed plate 15 the ammunition is drawn towards the gun without the assistance of the sprockets 5 because the plate is depressing a pin 17 serving to open the switch 12. As the loop, and therefore the plate 15, lifts however, the pin 17 disengages the switch and the motor drives the sprockets. The drive continues after firing ceases until the loop once again depresses the plate 17.
